Abstract
This paper presents a study of the degradation and biocompatibility behaviors of fully covered biodegradable polydioxanone
biliary stents (FCBPBSs) developed for human body. To investigate the relationship between the mechanical
property of FCBPBSs and degradation time, nine FCBPBSs were prepared both by braid-hand method using a
self-made cylinder of copper pipe mold and electrospinning. Meanwhile, the response of quality of FCBPBSs with
increasing of degradation time was investigated. Futhermore, FCBPBSs and cells were cultured together to study the
biocompatibility of FCBPBs indicating good biocompatibility.

Abstract
In this study, performance properties of single jersey knitted fabrics made from Aegean cotton, Supima cotton and Giza
cotton yarns are investigated. Firstly, Uster parameters and breaking strength of the yarns were examined and then the
properties of the fabrics knitted from these yarns were evaluated statistically. The significance levels of the relationship
between the measured parameters were determined. Considering the results obtained with the mechanical properties
of the fabrics with Uster analysis applied to these yarns, it is seen that the yarns made from Supima and Giza cotton
fibers in extra long fiber category have more smooth, less hairiness, contain less neps and the fabrics knitted with these
yarns have high mechanical properties.

Abstract
Color blended rotor spun yarn mixing with different methods were spun. Three blending methods were used, one
passage of drawing, three passages of drawing and rovings during multi-channel spinning. Multi-channel spinning is
modified on rotor spinning machine, which is implemented by a novel mechanical system specially designed to
incorporate three separate feed rollers side by side and controlled by servo motors with PLC. Using this new method,
blend ratio of yarn can be controlled and realized by asynchronous drafted rovings. 37 type of color blend yarn were
produced with different blending ratios. And each yarn was intercepted with 5 cross sections and a total of 185
cross-sectional images were taken. Hamilton index of different colored fibers were calculated of the each type of yarns.
And sum of absolute values of Hamilton index were got to demonstrated fibers blending effect in yarns cross sections.
All the Hamilton index of the yarns prepared by the three above mentioned methods were all around 5, much below 20.
The results showed that regardless of blending method used, the blending effects of rotor spun yarns were all very good.

Abstract
The basalt fibers/poly (lactic acid) composites, as a kind of green environment friendly materials, were prepared by
vacuum perfusion method. The effect of silane coupling agent KH550 on the interface of BFs/PLA composites was
analyzed. We observed the microstructure of the surface of BFs treated by silane KH550 and the interface of the
composites, explored the chemical reaction among silane KH550, BFs and PLA. The silane KH550 succeeded in linking
BFs and PLA and enhanced the interfacial bonding strength between BFs and PLA matrix. The crystalline properties of
KH550-treated BFs/PLA composites were better than untreated BFs/PLA composites. The mechanical test suggested
the silane KH550 had good effect on strengthening BFs/PLA composites.

Abstract
In this study, the commercial organophosphorus compound Pyrovatex CP New was used as a flame retardant for cotton
fabric. Citric acid and a modified dihydroxy ethylene urea (DHEU) labelled Knittex FFRC were used as crosslinking to
increase the flame-retardant laundering durability of treated cotton fabric. There have been some studies showing that
Chitosan has the potential to improve flame retardancy and laundering durability of flame retardant treated cotton fabric.
Thus, Chitosan, which has the molecular weight of 2.600 (water soluble) and the deacetylation degree of approximately
75%, is added to finishing solution for flame retardant treatment of cotton fabric. The padding-drying-curing method was
used in this study. After treatment, all samples were examined to determine the chemical absorption level. The 45°
flammability test characteristics and LOI value of untreated and treated samples after different number of washing cycle
were determined to assess the flame retardancy of the treated fabric and its laundering durability. In addition, to assess
the impact of this treatment on the mechanical strength and ecology of the fabric, the tensile strength and free
formaldehyde content of the treated fabric were also evaluated.

Abstract
The goal of the study is to develop a novel method to manufacture the functional bras. The high precision
three-dimensional (3D) scanner was employed to get the point cloud data. A fixed mount was invented to keep the bra
cup stable and decrease measuring error. A bottom holder was prepared by the 3D printer to place the bra cup during
the injection process. Furthermore, the injection points coordinate values and the injection volumes can be determined
based on the 3D image of the bra cup and the thickness of those positions. At last, the three-axis automatic robot which
was coupled with a precision liquid dispenser is used to inject the microcapsules solution into the bra cup for the
preparation of functional intimate apparel. The proposed method was verified to be feasible and effective through a
practical example.

Abstract
The textile industry of clothing causes professional diseases in particular the musculoskeletal disorders (MSDs). The
application of the culture of technical ergonomics and the methods of ergonomic analysis is to reduce the risk of the
diseases. The main objective of this study is to elaborate a rest index which allows giving a recovery period for the
sewing post to reduce the risk of MSDs. The method of experimental designs is used to find a model which contains the
parameters: the force multiplier, the frequency of technical actions per minute, the posture multiplier and the recovery
period multiplier. Then the analysis of results was done by MINITAB Software. The method of General Sewing Data is
used to analyze the gesture of the technical actions. The standard ISO 11228-3 is used to determine the posture
analysis and the recovery period multiplier. Then, the force analysis is realized by the Borg Score. The model proposed
is statistically significant (p value = 0), representative (R2 = 96.5%) and validated according to the predictor Fisher test.
The practical study was made in two companies of clothing to validate the rest index which varies between 1.14 and
1.22.

Abstract
This paper proposes a new Lean Six Sigma (LSS) methodology to improve process for clothing small- and
medium-sized enterprise SME. The methodology is based on combination of two approaches which are the PDCA
(Plan, Do, Check, and Act) and the DMAIC (Define, Measure, Analyze, Improve, and Control). The combination
technique consists in applying the PDCA to continuously improve and control every DMAIC steps. The DMAIC approach
has included Lean Six Sigma tools and techniques, as well as the success factors obtained from a survey, to improve
its efficiency. The proposed approach is applied to improve the performances indicators such as Z sigma, Cp, cycle time,
and lead time for the case of clothing SME in Tunisia. As an example, the Z-sigma has increased from the sigma level
was improved from 1.45 to 3.85. The process capability Cp from 0.5 to 1.3 and the lead time was decreased from 39.47
days to 30.23 days. Finally, the study is concluded by sorting out the effects of the type of produced articles and the
presence or not of the quality certification on the application of the proposed approach. The effectives from using PDCADMAIC
technique are better when it’s applied with certified company, than non-certified one.

Abstract
The properties of textured POY PES multifilament yarns are conditioned by texturing temperature, texturing speed,
stretching degree and by the ratio of disc peripheral speed and yarn speed. In the paper attention is focused on crimping
of yarns. New method for defining crimping limits is proposed. The method is based on the flow analysis of the
force-elongation function. POY multifilament polyester yarns, having the fineness of 167f36x1 dtex were analyzed. The
texturing of PES multifilament yarns was performed using different first heater temperatures (350 oC, 400 oC, 450 oC)
and maintaining the constant temperature of the second heater (180 oC), then with different texturing speeds
(500 m/min, 600 m/min, 700 m/min, 900 m/min, 1000 m/min, 1100 m/min), using different ratio of the disc circumferential
speed to yarn speed (2.15, 2.20, 2.25) and at the extension degree of 1.665.

Abstract
Conveyor belt production requires good adhesion between coating layer and fabrics. Adhesion is important for good
mechanical properties of belts. Silicone rubber has gained importance in food carrying because it is harmless when
being in contact with food materials. The aim of this study is to enhance the problematic adhesion properties between
polyester fabrics and silicone rubber coating by plasma treatment. The fabrics are modified by air or argon RF plasmas
under different power and time conditions. Influence of plasma parameters was investigated by adhesion strength tests.
To investigate changes on adhesion, wettability measurements, X-ray photoelectron spectrometry (XPS), Atomic Force
Microscopy (AFM), scanning electron microscopy (SEM) were performed untreated and plasma treated polyester
fabrics. After plasma treatments, the coating adhesion between fabric and coating polymer was increased approximately
for 4.6 times for argon and 4.3 times for air plasmas.
